[PATCH 05/16] Eliminate literal line numbers in ending-run.exp

[Andreas Arnez <arnez@linux.vnet.ibm.com>]

Remove literal line numbers from the regexps in ending-run.exp.  Add
appropriate eye-catchers to ending-run.c and refer to those instead.

gdb/testsuite/ChangeLog:

	* gdb.base/ending-run.c: Add eye-catchers.
	* gdb.base/ending-run.exp: Refer to eye-catchers instead of
	literal line numbers.
